The scope was to prepare detailed project report (DPR) with designs, drawings, and cost estimates for 61 new and 12 rehabilitated bridges, to enable quick restoration of communication in remote areas after the disastrous floods in Jun 2013 in Uttarakhand. As a result of the Jun 2013 disastrous floods starting from Kedarnath valley a large number of bridle bridges (for mules and pedestrian) were either washed away or damaged. The locations of these bridges were in far flung areas and many in high altitude regions, some under snow cover. Without motorable access, it required carriage of bridge parts and other stores man packed or on mules for both recconosance and when carrying stores for construction. The designs, had to cater for this. Many bridges had to be designed as motorable bridges also. It therefor involved designs of multiple types of bridges including Suspension, Steel Truss and Box Type of varying spans, maximum being 200 mtr multi span motorable bridge across a river. A number of innovative changes were needed keeping in mind the local requirements and terrain conditions, to allow for safety and convenience of the users. The Acrow motorable bridge was the most prominent amongst these. A major and bold introduction was the New Technology Modular Acrow Bridge, that was launched in one month to give a two lane, motor bridge for Cl 70R loading with sidewalks on both sides. This was a shift from using the Bailey Bridge which was earlier the only option for emergencies, but unsafe and not suited for IRC loads.
